Detailed description of the invention
The following is specific embodiments of the invention and in conjunction with accompanying drawing, technical scheme is further described, but the present invention is not limited to these embodiments.
As shown in Figures 1 to 4, this Multi-angle hydraulic pipe bender includes frame 1, frame 1 is provided with the hydraulic cylinder 2 of horizontal positioned, about two pressing plates 3 be arrangeding in parallel and hydraulic cylinder 2 piston rod end it is provided with between two pressing plates 3 in hydraulic cylinder 2 front end, it is provided with two moving blocks 4 between two pressing plates 3 and two moving blocks 4 are symmetricly set on hydraulic cylinder 2 piston rod both sides, two pressing plates 3 offer multiple location hole 3a being symmetrical set and is in that hole, the location 3a of pressing plate 3 the same side is dip-parallel is arranged in multiple row, moving block about 4 two ends are inserted respectively admittedly in corresponding hole, location 3a and can circumferentially rotate, guide post 5 is installed in frame 1 side and on guide post 5, is provided with stopper 6, and the end of tubing can be resisted against on stopper 6 when tubing is through gap two pressing plates 3.
By moving block 4 being arranged between two pressing plates 3, so that tubing moving block 4 when being curved work does not have the phenomenon rocked, ensure stability during work, moving block 4 can circumferentially rotate simultaneously, make tubing when flexural deformation, moving block 4 rotates and drives tubing to be originally resisted against the position of moving block 4 and moves to hydraulic cylinder 2 piston rod moving direction along with bending work, it is to avoid tubing stuck phenomenon occurs when mobile or owing to moving block 4 firmly contacts the situation causing outer pipe wall to cave in outer pipe wall with moving block 4.
When hydraulic cylinder 2 piston rod stroke is constant, moving block 4 insert solid same a line or with hole, the location 3a of string in time, moving block 4 is the closer to cylinder piston rod, and tubing flexibility is more little.
When tubing is curved work by needs, first the position of crooked position is needed to adjust the stopper 6 position on guide post 5 according to tubing, diameter and tubing further according to tubing need the angle of bending to adjust the slotting solid concrete position positioning hole 3a on pressing plate 3 of moving block 4 needs, finally tubing it is inserted in two pressing plates 3 and makes pipe end be resisted against on stopper 6, start hydraulic cylinder 2, by hydraulic cylinder 2 piston rod, tubing is applied a thrust so that Tube Bending Deformation.
Further, the pressing plate 3 being positioned below is fixedly mounted in frame 1, and pressing plate 3 above is hingedly connected on hydraulic cylinder 2, and moving block 4 is axially fixed on pressing plate 3 by bolt.When adjusting the moving block 4 position on pressing plate 3, need moving block 4 is inserted the solid pressing plate 3 positioned at other on 3a of hole, after therefore first being unscrewed by moving block 4, above opening, moving block 4 is plugged on corresponding hole, location 3a again, finally covers pressing plate 3 and again screw moving block 4.
Further, moving block 4 periphery wall offers the equally distributed arc groove 4a of multiple circumference, when tubing is interspersed between two pressing plates 3, start hydraulic cylinder 2, hydraulic cylinder 2 piston rod withstands on the outer wall of tubing and tubing is curved work, now the stress point on tubing is except the position that hydraulic cylinder 2 piston rod withstands on tubing place, two stress points are also had to be the position that tubing is resisted against on moving block 4, by being opened in the arc groove 4a on moving block 4 periphery wall, make tubing periphery wall be resisted against in arc groove 4a and with arc groove 4a at the bottom of plane-plane contact, thus increasing the contact area of tubing periphery wall and arc groove 4a, avoid the pressure that tubing bears in BENDING PROCESS excessively to concentrate and cause the situation of pipe deformations.
Further, stopper 6 is fixed on guide post 5 by bolt is sheathed, when the position needing adjustment tubing to need crooked position, first unscrew bolt, making stopper 6 be moved axially until stopper 6 along guide post 5 needs crooked position with hydraulic cylinder 2 piston rod vertical line distance to the distance of pipe end for tubing, owing to hydraulic cylinder 2 piston rod to frame 1 sidewall (this sidewall and frame 1 are for installing the sidewall of guide post 5) air line distance is constant, therefore stopper 6 and hydraulic cylinder 2 piston rod vertical line distance are the distance of stopper 6 to frame 1 sidewall and are tubing plus the air line distance of hydraulic cylinder 2 piston rod to frame 1 sidewall and need crooked position to the distance of pipe end；Now stop mobile stopper 6, and screwing bolts makes stopper 6 retighten on guide post 5 again, then tubing it is inserted between two pressing plates 3 and makes pipe end be resisted against on stopper 6, now tubing faces the position of hydraulic cylinder 2 piston rod and is tubing and needs the position of bending, this structure is accurately controlled tubing needs the site location of bending, it is to avoid the long situation needing cutting to cause the wasting of resources in its one end after bending pipes.
Further, being carved with scale on guide post 5, by the scale on guide post 5, crooked position can be needed to come the accuracy controlling stopper 6 position at guide post 5 to the distance of pipe end according to tubing, degree of accuracy is high.
Further, hydraulic cylinder 2 is provided with a mounting seat 10, the screw rod 8 be arrangeding in parallel with hydraulic cylinder 2 piston rod it is interspersed with in mounting seat 10, and the head end of screw rod 8 is connected with hydraulic cylinder 2 piston rod by contiguous block, the threads of screw rod 8 be connected to adjusting nut 9 and when screw rod 8 moves axially adjusting nut 9 can be resisted against in mounting seat 10.Man-hour is added the tubing of diameter of the same race is curved, when moving block 4 is arranged on the invariant position on pressing plate 3, the stroke of hydraulic cylinder 2 piston rod is regulated by adjusting the adjusting nut 9 position on screw rod 8, hydraulic cylinder 2 piston rod stroke is different, tubing is curved the flexibility of bending pipes part during work also different.
Further, being fixed with arc jacking block 7 in hydraulic cylinder 2 piston rod end, the arcwall face of arc jacking block 7 faces hydraulic cylinder 2 piston rod and ejects direction, and circumferentially direction offers arcuate groove 7a on this arcwall face.When piston rod ejects, the arcuate groove 7a on arc jacking block 7 is resisted against on the outer surface of tubing so that arc jacking block 7 contacts with tubing face, it is to avoid the thrust that tubing bears in BENDING PROCESS is excessively concentrated and caused the situation of pipe deformations.
Specific embodiment described herein is only to present invention spirit explanation for example.Described specific embodiment can be made various amendment or supplements or adopt similar mode to substitute by those skilled in the art, but without departing from the spirit of the present invention or surmount the scope that appended claims is defined.
